A letter report issued by the Government Accountability Office with an abstract that begins "Of the 66 old federal courthouses that GAO reviewed, the General Services Administration (GSA) retained 40, disposed of 25, and is in the process of disposing of another. Of the retained old courthouses, the judiciary occupies 30 of them, 25 as the main tenant, most commonly with the district and bankruptcy courts. When determining whether to retain and reuse or to dispose of old courthouses, GSA considers, among other things, a building's condition, the local real estate market, and the existing and projected base of federal tenants. GSA officials said that after the judiciary moves to new courthouses, old courthouses often require renovations to be reused. Moreover, GSA officials said that it can be challenging to find new tenants for old courthouses due to the buildings' condition and needed renovations, among other reasons. Among the retained old courthouses GAO reviewed, excluding one building that was under major renovation, about 14 percent of the total space (nearly 1-million square feet) in them was vacant as of May 2013--significantly higher than the 4.8 percent overall vacant space in federally-owned buildings in 2012."

A letter report issued by the Government Accountability Office with an abstract that begins "The four main U.S. agency Afghan development programs and accounts have similar goals and activities and hence overlap to some degree. In fiscal year 2011, the Economic Support Fund (ESF) and other smaller accounts administered by the U.S. Agency for International Development (USAID), and the Commander's Emergency Response Program (CERP), administered by the Department of Defense (DOD), funded similar activities related to agriculture; democracy and governance; education and health; energy and electricity; economic growth; and transportation. Both funded activities in 33 of Afghanistan's 34 provinces and in 249 of Afghanistan's 399 districts. The Task Force for Business and Stability Operations (TFBSO), administered by DOD, and the Afghanistan Infrastructure Fund (AIF), administered by DOD and the Department of State (State), also funded efforts in some of the same categories of assistance as ESF and CERP in fiscal year 2011. According to agency officials, these overlapping development efforts can be beneficial, provided that agencies leverage their respective expertise and coordinate efforts."

A letter report issued by the Government Accountability Office with an abstract that begins "Each year the federal government spends billions of dollars on information technology (IT) investments. Given the importance of program oversight, the Office of Management and Budget (OMB) established a public website, referred to as the IT Dashboard, that provides detailed information on about 800 federal IT investments, including assessments of actual performance against cost and schedule targets (referred to as ratings). According to OMB, these data are intended to provide both a near-real-time and historical perspective of performance. In the third of a series of Dashboard reviews, GAO was asked to examine the accuracy of the Dashboard's cost and schedule performance ratings. To do so, GAO compared the performance of eight major investments undergoing development from four agencies with large IT budgets (the Departments of Commerce, the Interior, and State, as well as the General Services Administration) against the corresponding ratings on the Dashboard, and interviewed OMB and agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Various options are available to make the Pension Benefit Guaranty Corporation's (PBGC) premium structure more risk-based and better reflect the risk of future claims. Historically, PBGC's premiums have not fully reflected the risks PBGC insures against--chiefly that a plan sponsor with an underfunded plan will become bankrupt, forcing the termination of the plan and imposing a claim on PBGC. PBGC's current structure relies largely on a flat-rate premium that is based on the number of plan participants and that assesses rates equally per plan participant across all sponsors. PBGC also charges a variable-rate premium that is based on just one risk factor, plan underfunding. One available option is to further increase rates within this current structure; however, plan underfunding alone is a poor proxy for the risk of new claims. An alternative option is to redesign premiums to incorporate additional risk factors, such as a sponsor's financial strength (as currently being explored by PBGC) or a plan's investment strategy (as is currently done in the United Kingdom)."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the use of test facilities as a means of leveraging public, private, and academic resources to deliver technologies for the Next Generation Air Transportation System (NextGen). NextGen will affect nearly every aspect of air transportation and will transform the way in which the air transportation system operates today. It is a complex undertaking that requires new technologies--including new integrated ground and aircraft systems--as well as new procedures, processes, and supporting infrastructure. The result will be an air transportation system that relies on satellite-based surveillance and navigation, data communications, and improved collaborative decision making. Transforming the nation's air transportation system affects and involves the activities and missions of several federal agencies, though the Federal Aviation Administration (FAA) is the lead implementer. In addition, NextGen was designed and planned to be developed in collaboration with aviation stakeholders--airlines and other airspace users, air traffic controllers, and avionics, aircraft, and automation systems manufacturers--in order to facilitate coordinated research activities, transfer technologies from FAA and partner agencies to the private sector, and take advantage of research and technology developed by the private sector that could meet NextGen needs, as appropriate. …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Housing and Urban Development's (HUD) Federal Housing Administration (FHA) has helped millions purchase homes by insuring private lenders against losses from defaults on FHA-insured single-family mortgages. In recent years, FHA has experienced a dramatic increase in its market role due, in part, to the contraction of other mortgage market segments. The increased reliance on FHA mortgage insurance highlights the need for FHA to ensure that it has the proper controls in place to minimize financial risks while meeting the housing needs of borrowers. In addition to providing data on FHA's single-family workload, GAO was asked to evaluate (1) FHA's risk assessment strategy, including the extent to which it is consistent with HUD and GAO internal control standards, and (2) steps FHA has taken to manage the risks in its single-family programs. To address these objectives, GAO analyzed data from fiscal years 2006-2010 on single-family business volume and workload, reviewed FHA documents on risk assessment and changes made to manage risks (such as those to human capital), and interviewed FHA officials."

Correspondence issued by the Government Accountability Office with an abstract that begins "Spending reductions under sequestration affected DOD’s civilian workforce and many programs and functions, and required DOD to accept some risk in maintaining the readiness of military forces. However, DOD was able to mitigate some near-term effects of sequestration on its mission. Reduced spending levels required DOD to take actions such as furloughing most civilian employees for 6 days, cancelling or curtailing training for units that were not preparing to deploy by early in 2014, postponing some planned equipment maintenance at its depots and repairs or renovations of facilities, reducing some weapon system quantities or deferring modifications, and delaying system development and testing. DOD took various actions to plan for and implement sequestration, such as issuing guidance and establishing processes to identify priorities and evaluate alternatives for spending reductions. Generally, DOD’s approach to sequestration was a short-term response focused on addressing the immediate funding reductions for fiscal year 2013. DOD was able to reduce spending levels for the remainder of fiscal year 2013 without making permanent changes, such as adjusting the size of its forces or canceling weapon systems programs. By setting priorities for funding and using available prior …

A letter report issued by the Government Accountability Office with an abstract that begins "According to U.S. Census Bureau (Bureau) officials, to inform timely design decisions, research on new methods to improve the cost effectiveness of the 2020 Census must be accomplished early enough in the decade to confirm their likely impact on both cost and quality. Three key efforts--(1) the use of the Internet as a response option, (2) a potential move towards targeted address canvassing, and (3) the possible use of administrative records to replace data collected during census field operations--present the Bureau with potential opportunities to reduce costs while maintaining quality. The Bureau's 2020 Research and Testing Program has 14 fiscal year 2012 projects focused on informing design decisions related to the three key efforts. Bureau officials are also aware that the changes they are testing come with many risks, and for each project the Bureau has identified a number of risks and prioritized them from high to low. However, the Bureau has not developed mitigation or contingency plans for these project risks. For example, there are several risks, including tight time frames and accurate cost information, without mitigation and contingency plans. Additionally, GAO found that the …

A new method is presented for solving Poisson's equation inside an open-ended rectangular pipe. The method uses Fast Fourier Transforms (FFTs)to perform mixed convolutions and correlations of the charge density with the Green function. Descriptions are provided for algorithms based on theordinary Green function and for an integrated Green function (IGF). Due to its similarity to the widely used Hockney algorithm for solving Poisson'sequation in free space, this capability can be easily implemented in many existing particle-in-cell beam dynamics codes.

This effort is part of the technetium management initiative and provides data for the handling and disposition of technetium. To that end, the objective of this effort was to challenge tin(lI)apatite (Sn(II)apatite) against double-shell tank 241-AN-105 simulant spiked with pertechnetate (TcO{sub 4}). The Sn(II)apatite used in this effort was synthesized on site using a recipe developed at and provided by Sandia National Laboratories; the synthesis provides a high quality product while requiring minimal laboratory effort. The Sn(ll)apatite reduces pertechnetate from the mobile +7 oxidation state to the non-mobile +4 oxidation state. It also sequesters the technetium and does not allow for re-oxidization to the mobile +7 state under acidic or oxygenated conditions within the tested period of time (6 weeks). Previous work indicated that the Sn(II) apatite can achieve an ANSI leachability index in Cast Stone of 12.8. The technetium distribution coefficient for Sn(lI)apatite exhibited a direct correlation with the pH of the technetium-spiked simulant media.

Integrated digital instrumentation and control (I&C) systems in new and advanced nuclear power plants (NPPs) will support operators in monitoring and controlling the plants. Even though digital systems typically are expected to be reliable, their potential for degradation or failure significantly could affect the operators performance and, consequently, jeopardize plant safety. This U.S. Nuclear Regulatory Commission (NRC) research investigated the effects of degraded I&C systems on human performance and on plant operations. The objective was to develop technical basis and guidance for human factors engineering (HFE) reviews addressing the operator's ability to detect and manage degraded digital I&C conditions. We reviewed pertinent standards and guidelines, empirical studies, and plant operating experience. In addition, we evaluated the potential effects of selected failure modes of the digital feedwater control system of a currently operating pressurized water reactor (PWR) on human-system interfaces (HSIs) and the operators performance. Our findings indicated that I&C degradations are prevalent in plants employing digital systems, and the overall effects on the plant's behavior can be significant, such as causing a reactor trip or equipment to operate unexpectedly. I&C degradations may affect the HSIs used by operators to monitor and control the plant. For example, deterioration of the sensors …

The Source Physics Experiment (SPE) will involve a series of explosions in various geologic and emplacement conditions to validate numerical simulation methods to predict behavior of seismic wave excitation and propagation for nuclear test monitoring. The first SPE's currently underway involve explosions in the Climax Stock (granitic geology) at the Nevada National Security Site (NNSS). Detailed geologic data and published material properties for the major lithologic units of the NNSS and surrounding region were used to build three-dimensional models for seismic wave propagation simulations. The geologic structure near the SPE shot point is quite varied including granitic, carbonate, tuff and alluvium lithologies. We performed preliminary ground motion simulations for a near-source domain covering 8 km x 8 km at the surface centered on the shot point to investigate various source and propagation effects using WPP, LLNL's anelastic seismic wave finite difference code. Simulations indicate that variations in wave propagation properties of the sub-surface will generate strongly path-dependent response once the energy has left the relatively small granitic geology of the near-surface Climax Stock near the SPE shot point. Rough topography to the north and west of SPE shot point causes additional complexity in the signals including energy on the transverse …
